To all whom it may concern:

Be it known that I, FREDERICK BENZ, J r., a citizen of the United States, residing at Haledon,in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Batten Structures for Narrow-Ware Looms, of which the following is a specification.

This invention relates to batten structures for narrow ware looms ofthe class in which the shuttles are arranged in two tiers one above the other, and in particular to batten structures of this class in which the shuttles move in straight paths. In the usual construction of such batten structures the upper and lower races are formed by pairs of blocks or strips, the blocks or strips in one tier being staggered with reference to those in the other tier, the vertically alined ends of each four blocks (two in each tier) being attached to an uprightsecured to the batten proper. i y

The present invention consists in forming each shuttle race element as a grooved block instead of as a pair of blocks or strips, and in providing the blocks so formed with recesses registering with the weaving spaces and so that the blocks in the upper tier have such recesses at their under sides and those in the lower tier have the recesses at their upper sides. This construction, while reducing the number of parts forming the races fifty per cent. and producing a much more sturdy and substantial structure than the present one, brings the upper and lower warp sheds nearer to the horizontal median plane, involving certain advantages to be hereinafter explained, and it permits the entire race-forming portion to be made materially lower than at present, as will be pointed out, so that the weaver can with greater facility than at present reach over and back- Fig. 7 is a. front-to-rear sectional view of a loom, showing the breast-beam, my im proved batten structure, the harness, the lease-rods, the rear-guidebar for the warps, and the two warps, illustrating how my invention makes it possible to hung the warps closer to ahorizontal plane between them and thereby employ a single pair of leaserods, instead of two pairs (one for each warp) as heretofore.

The batten proper a has uprights b attached to the back thereof, and also the usual groove 0 for the lower rack (Z. Attached to the uprights over the groove is a bar 0 grooved at f to receive the upper rack g. The racks may be reciprocated in any well known manner.

h designatesthe lower set of blocks, and i the upper set. Each block is formed with a groove (h 2') of suitable sectional contour to properly guide the shutttles (lower and upper) j and 70, which respectively travel therein; each block also has journaled in suitable cavities therein and on the tubular bearings Z a pair of pinions on, those of the upper blocks having their peripheries protruding both into the grooves 71 and at the tops thereof and those of the lower blocks having their peripheries protruding both into the grooves h and at the bottoms thereof, whereby the teeth of said pinions will engage the racks d and g and the racks of the shuttles so that when the racks are reciprocated the shuttles will be driven in the well known manner. Each block is formed of a single piece of material, as wood.

Recesses n and 0 are formed in the blocks 71, and i in their upper and lower faces, respectively, each recess being located centrally of its block and of a width conforming to that of the (weaving) spaces between them. The recesses o of the upper blocks are beveled upwardly and rearwardly and those a of the lower blocks downwardly and rearwardly, as best shown in Figs. 5 and 6. Each side of the recess in each block a table p is left, afi'ording a broad bearing surface which is preferably perpendicular to the back face 9 of the block. The upper face r of each upper block and the lower face 8 of each lower block afford broad fiat bearing surfaces perpendicular to the back face, eX- cepting for a forward depending flange s on the lower block coverin the rack 0Z-and in this connection it may e remarked that back of the rack 03 the batten proper has an upstanding flange a.

- The two sets of blocks, each secured to a pair of uprights by four screws If (two of which penetrate the I bearings Z of each block), are arranged so that the two'tables p of each upper block bear squarely against the adjoining tables 39 of the corresponding two lower blocks; and so that, further, each lower block rests at the back on the flange a and at the front has its flange 8 bearing on the batten proper, and each upper block has the rack g and grooved bar 6 bearing squarely upon its top face. 1 It will be apparent that a very durabl and substantial construction results from my invention, especially as grooved blocks are used instead of spaced pieces to form the races- By providing such grooved blocks, moreover, instead of spacedstrips I can and do without materially weakening the adj oining race-forming walls extend the upper weaving spaces downwardly and the lower weaving spaces upwardly until they reach appreciably past the median horizontal plane, which makes it possible for the two sets of warps, of course, to be brought considerably closer to such plane; and that being achieved, I can further very materially reduce, and in the present construction herein illustrated in fact have materially re duced, the height of the whole structure, which is a great advantage in itself in making it more convenient for the weaver in this (so-called double-deck) type of batten structure to reach over and back of the same.

In actual practice I have found it possible, as shown in Fig. 7 ,for both the upper and lower warps to have a cross-forming means, as the lease rods u, in common; this is not'po'ssible with the present construction of battensof the class to which my inven tion relates because they require the upper and lower sets of warps to-be spaced-so corisiderably that if they had a cross-forming means in common the necessary bend in each warp would be so great as to-produce a pro hibitive strain thereon.

.Having' thus fully described my invention, whatI claim and desire to secure by Letters Patent is:

In combination, with the batten proper, a

race-forming structure upstanding there- 7 from and including twotiers of spaced blocks superimposed one upon'the other and so that the spaces between the blocks in each tier register with the blocks in the other tier, each-upper block having in its under side and each lower block having in its upper side a recessconforming with the space registering with such block, and said spaces forming weaving spaces and the blocks in each tier havingv alined' shuttleguiding: groovesin a plane traversing the spaces between them. 7 In testimony. whereof- I aflix mysignature.
